Feature #15743
Updated by Eregon (Benoit Daloze) over 5 years ago
My understanding is that `RubyVM` is supposed to only exist on MRI/CRuby, and not on any other Ruby implementation. In fact, almost all features under `RubyVM` are not realistically implementable on other major Ruby implementations (JRuby, TruffleRuby, Rubinius). Unfortunately, the name doesn't reflect that it is specific to CRuby, e.g., JRuby/TruffleRuby/Rubinius are also "Ruby VMs". And as a result it is not clear for many Ruby users that RubyVM is CRuby-specific. The documentation is also unclear: ``` The RubyVM module provides some access to Ruby internals. This module is for very limited purposes, such as debugging, prototyping, and research. Normal users must not use it. ``` So I propose to rename RubyVM to CRuby. That way, it is clear for everyone that this module is CRuby-specific. It's also consistent with the JRuby module, the TruffleRuby module and the Rubinius module. Proposed migration path: * Introduce CRuby as an alias of RubyVM on `trunk`, and deprecate the RubyVM constant on `trunk` (for 2.7). the MRI 2.7 release). * Remove `RubyVM` in Ruby 3.0.
